Pinout

Pin	Name	Type	Function
1	BOOT0	input	Boot mode select input sampled at reset. Selects boot-from-main-flash, system-memory (bootloader), or SRAM together with the nBOOT1 option bit.
2	PF0-OSCIN	bidirectional	General-purpose I/O PF0 (5 V tolerant). Alternate: I2C0_SDA. Additional: OSCIN (HXTAL crystal input).
3	PF1-OSCOUT	bidirectional	General-purpose I/O PF1 (5 V tolerant). Alternate: I2C0_SCL. Additional: OSCOUT (HXTAL crystal output).
4	NRST	bidirectional	Active-low device reset. Bidirectional pin driven low internally on any reset source and can be driven low externally to reset the MCU.
5	VDDA	power_in	Analog supply for the ADC, comparators, reset block, and PLL. Operating range 2.6 V to 3.6 V; must be tied to VDD when analog blocks are used.
6	PA0-WKUP	bidirectional	General-purpose I/O PA0. Alternates: USART0_CTS/USART1_CTS, CMP_OUT, I2C1_SCL. Additional: ADC_IN0, CMP_IM6, RTC_TAMP1, WKUP0 (wake-up from Standby).
7	PA1	bidirectional	General-purpose I/O PA1. Alternates: USART0_RTS/USART1_RTS, I2C1_SDA, EVENTOUT. Additional: ADC_IN1, CMP_IP.
8	PA2	bidirectional	General-purpose I/O PA2. Alternates: USART0_TX/USART1_TX. Additional: ADC_IN2, CMP_IM7.
9	PA3	bidirectional	General-purpose I/O PA3. Alternates: USART0_RX/USART1_RX. Additional: ADC_IN3.
10	PA4	bidirectional	General-purpose I/O PA4. Alternates: SPI0_NSS, I2S0_WS, USART0_CK, USART1_CK, TIMER13_CH0, SPI1_NSS. Additional: ADC_IN4, CMP_IM4.
11	PA5	bidirectional	General-purpose I/O PA5. Alternates: SPI0_SCK, I2S0_CK. Additional: ADC_IN5, CMP_IM5.
12	PA6	bidirectional	General-purpose I/O PA6. Alternates: SPI0_MISO, I2S0_MCK, TIMER2_CH0, TIMER0_BRKIN, TIMER15_CH0, EVENTOUT, CMP_OUT. Additional: ADC_IN6.
13	PA7	bidirectional	General-purpose I/O PA7. Alternates: SPI0_MOSI, I2S0_SD, TIMER2_CH1, TIMER13_CH0, TIMER0_CH0_ON, TIMER16_CH0, EVENTOUT. Additional: ADC_IN7.
14	PB1	bidirectional	General-purpose I/O PB1. Alternates: TIMER2_CH3, TIMER13_CH0, TIMER0_CH2_ON, SPI1_SCK. Additional: ADC_IN9.
15	VSS	power_in	Device ground / digital return (0 V).
16	VDD	power_in	Main digital supply, 2.6 V to 3.6 V. Powers the digital core, I/O ring, and embedded voltage regulator; decouple locally.
17	PA9	bidirectional	General-purpose I/O PA9 (5 V tolerant). Alternates: USART0_TX, TIMER0_CH1, I2C0_SCL, CK_OUT.
18	PA10	bidirectional	General-purpose I/O PA10 (5 V tolerant). Alternates: USART0_RX, TIMER0_CH2, TIMER16_BRKIN, I2C0_SDA.
19	PA13/SWDIO	bidirectional	PA13, default function SWDIO (Serial Wire Debug data). Alternates: IFRP_OUT, SPI1_MISO. 5 V tolerant.
20	PA14/SWCLK	bidirectional	PA14, default function SWCLK (Serial Wire Debug clock). Alternates: USART0_TX, USART1_TX, SPI1_MOSI. 5 V tolerant.

CAD (KiCad official)

Symbol: GD32E230F6P6TR
Footprint: Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm
3D model: TSSOP-20 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gd32e230f6p6tr.step`	267 KB	You want the bare part, or you mark your own boards.
`gd32e230f6p6tr-etched.step`	3.7 MB	You want the part with `GD32E230F6P6TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 896 faces against 327 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
